Heres asolution for it!!!!!!!!!!!
While grinding dosa batter in mixy jar, add Rice flakes/atukulu (1/2 cup), if not borugulu(murmuras), or menthulu (fenu greek seeds, 4-5), and grind finely, dosa will come out so softly. Check urself and see the difference.

Cut onion top as an round piece, rub it on the dosa pan and then make dosa on it, dosa will come without any cuts/breaks
